Javascript - JQuery Ajax Cross Domain Call And Permission

Feb 4, 2010

I have this polling script to check if a text file is created on the server. Works great locally, but fails when the file is on a different domain. How would i rewrite this for cross domain support?

$.ajax({
url: 'http://blah.mydomain.com/test.txt',
type: "GET",
success: function(result) {
//Success!
window.location.replace(Successful.aspx');
},
error: function(request, status, error) {
setTimeout("VerifyStatus(" + pollingInterval + ")");
}
});

EDIT: I ended up using YQL to solve the cross domain issue and although it works, YQL is really slow that's adding quite a bit of performance overhead. Can anyone suggest a better solution for cross domain JQuery calls?

Cross Domain Call Not Working In FireFox And Chrome?

Nov 16, 2010

I am making a asynchronous request to different server for some data using jquery. It works fine in IE, but doesn't work in FireFox and Chrome, when it reaches the code where the request to other server is made, it freezes there and a blank page is shown. If I remove that piece of code, the ajax works fine.

Also, when I place a breakpoint at document.ready, the breakpoint is hit when debugging using IE, but it's not hit when debugging using FireFox.

Following is the JQuery I am using

jQuery(document).ready(function ($) {

$('.tabs a, .tabs span').livequery('click', function () {[code]....

I am trying out jsonp with jQuery. I found many examples on the web and I believe my code is correct, but its still not working for me.

JavaScript - Cross Domain Requests Using JQuery?

Sep 1, 2010

This is a followup question to the one here

Here's briefly what I am trying to do. The File server creates a text file to indicate an end of the process. On a webpage on the Web Server, I loop every x seconds and make an ajax request to find out if the test file exists (ajax request to [URL]

I've tried the following approaches so far:

Trigger a web method from the client side that creates a HttpContext object to verify if the text file exists. But this is too strenous on the server and I started getting all kinds of exceptions in the Event Viewer.

Jsonp Cross Domain Only Working In IE

Apr 28, 2010

EDIT: At first I thought it wasn't working cross domain at all, now I realize it only works in IE. I'm using jQuery to call a web service (ASP.NET .axmx), and trying to us jsonp so that I can call it across different sites. Right now it is working ONLY in IE, but not in Firefox, Chrome, Safari. Also, in IE, a dialog pops up warning "This page is accessing information that is not under its control..."

$.ajax({
type: "POST",
[URL],
dataType: "jsonp",
success: function(data) {
alert(data.prop1);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status + " " + textStatus + " " + errorThrown);
}
});

And the server code is:

[ScriptService]
public class TestService : System.Web.Services.WebService{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void HelloWorld() {
string jsoncallback = HttpContext.Current.Request["jsonp"];
var response = string.Format("{0}({1});", jsoncallback, @"{'prop1' : '" + DateTime.Now.ToString() + "'}");
HttpContext.Current.Response.Write(response);
}
}

C# - How To Post Data To Another Web Application (cross Domain)

Jan 21, 2010

There are two web applications App1 & App2. A user would submit his information on App1 though a form. On click of a specific button/link on App1, the same data should be posted to a page on App2 and the user should also be redirected to the same page on App2.I would like some help in finding out the best way to implement this functionality.

One of the approaches that I have already tried out is by creating a temporary HTML form at runtime, setting the action attribute of the form to the App2 Page and get the form posted by using javascript submit. The data can then be fetched on App2 page by using the response.form object.This approach works well, but i was still wondering if there is any other way to implement the required functionality.

give some insights on using RESTful webservices to implement this, or else, using some HttpModule to intercept requests at App1 and modify redirect response to app2 or any other approach that you might find fit for the purpose.

Edit: Using querystring isnt an option for me.

How To Display Cross Domain Content In IFrame (IE8)

Mar 15, 2010

I realized that IE8 does not allow links from cross domains to be displayed in IFrame.
It seems like there are only two Header options that Microsoft allows to modify.

X-FRAME-OPTIONS : "DENY" (This does not display any IFrame content )
X-FRAME-OPTIONS : "SAMEORIGIN" (Displays content from the same domain)

Is there a work around to allow content from other domains to be displayed?

Geolocation Information With Asp.net Mvc (cross Domain Security)

How can I get a user's geolocation information (City and Country - internet service provider and internet speed would also be great) based on their IP address?

I've searched and found several tools for doing this but I seem to run into problems using them with asp.net mvc. Many of them relate to using json and the "security risk" involved in cross domain ajax calls.

C# - .NET Cross-Sub-Domain Single Sign-On Cookies

Oct 28, 2010

I have a Single Sign-on solution which is working great in our test environment. It uses Cross-Sub-Domain cookies to share the authentication ticket between 2 web applications. Sign-on is done only on one of the applications and on the second site the user is authenticated by the cookie created by the first site.The problem is that when I roll it into the production environment the single sign-on no longer works. I'm looking for any ideas on why this might be. More details below:1) Both apps are implemented using ASP.NET MVC2

WIF Cross-domain On One IIS Site/ Dynamically Setting Of Realm?

Nov 16, 2010

We have a lot of domains running on one IIS WebSite/AppPool.

Right now we are in the process of implementing SSO with Windows Identity Foundation.

in web.config the realm has to be set with

<wsFederation passiveRedirectEnabled="true" issuer="http://issuer.com" realm="http://realm.com" requireHttps="false" />

My problem is that the realm is dependent on which domain the user accessed the website on so what I did is that I set it in an global action filter like this

var module = context.HttpContext.ApplicationInstance.Modules["WSFederationAuthenticationModule"] as WSFederationAuthenticationModule;
module.Realm = "http://" + siteInfo.DomainName;

My question is. When I set the realm like this, is it set per user instance or application instance.

Scenario.

User A loads the page and the realm get set to domain.a.com.

User B is already logged in on domain.b.com and presses login.

Since user A loaded the page before User B pressed login, user A will hit the STS with the wrong realm set.

What will happen here?

If this is not the way to set the realm per user instance, is there another way to do it?

State Management :: Preserve __viewstate Between Cross Domain Posts?

Aug 20, 2010

Here is what I want to do: I have a local site in which I want to display data from a remote site
Lets say: I want to display data of http://www.abc.com/Default.aspx on my localhost

Now Default.aspx requires some post-data which it sends to itself. Thus the __viewstate and __eventvalidation are posted back to it by itself. I want to directly post the data to Default.aspx from localhost without opening Default.aspx and display the Default.aspx's response on my localhost.

The WebApp on http://www.abc.com is configured for __eventvalidation i.e. I cannot post-data to it from my localhost without getting a __viewstate from it. I also have to post the current __viewstate of http://www.abc.com/Default.aspx to itself
